以硅球为模板，采用溶剂热法合成了异形（可变形）中空g-C3N4纳米球。产物的x射线衍射（XRD）峰指向g-C3N4材料。场发射扫描电镜和透射电镜证实，空心纳米球的外径约为130 ~ 150nm，壁厚约为。20 - 30 nm。FTIR光谱显示，吸收峰位于810 cm（-1）处，可归因于s-三嗪（C3N3）的呼吸方式。拉曼光谱在1360 cm(-1) （D波段）和1580 cm(-1) （C波段）有两个宽峰。变形的饼状或空心球体臼状首次报道。可变形中空g-C3N4纳米球的柔韧性可用于药物递送载体等特殊领域，可通过外部压力调节递送比，是研究sp(2)杂化g-C3N4力学性能的良好材料。产物的光致发光光谱表明，该可变形中空g-C3N4纳米球在纳米光学器件领域具有潜在的应用前景。(C) 2011 Elsevier B.V.版权所有
Special shaped (deformable) hollow g-C3N4 nanospheres were synthesized by the solvothermal technique using silica spheres as template. The X-ray diffraction (XRD) peaks of the product were indexed to g-C3N4 materials. Field-Emission Scanning Electron Microscopy and Transmission Electron Microscopy confirmed that the external diameter of the hollow nanospheres is about 130-150 nm and thickness of the wall is about. 20-30 nm. The FTIR spectrum showed absorption peak at 810 cm(-1) can be attributed to the s-triazine (C3N3) breathing mode. Raman spectrum exhibited two broad peaks approximately at 1360 cm(-1) (D band) and 1580 cm(-1) (C band). The deformed pie shape or mortars like hollow spheres were first reported. The flexility of the deformable hollow g-C3N4 nanospheres may be used in special field such as drug delivery carriers adjusting the delivery ratio by the external pressure, and a good material for studying the mechanical Properties of the sp(2) hybrid g-C3N4. The photoluminescence spectrum of the product indicates that the deformable hollow g-C3N4 nanospheres may have potential applications in nano-optical device fields. (C) 2011 Elsevier B.V.
